Description

Technical Field

[0001] This utility model relates to the field of cardboard box production, and more specifically, to an adjustable height cardboard box punching device. Background Technology

[0002] Cardboard boxes are lightweight packaging containers made of corrugated cardboard. They typically consist of a flat kraft paper surface layer and a corrugated core layer bonded together to form a multi-layered composite structure. They are lightweight, pressure-resistant, shockproof, and low-cost. Their main functions are to provide protection for goods during transport, dust and moisture protection, and stacking support. They are widely used in logistics, e-commerce, food, and electronics industries. Furthermore, due to their recyclable and biodegradable properties, they are considered an environmentally friendly packaging material.

[0003] The holes in cardboard boxes are usually made during the cardboard processing stage (i.e., before folding into a box) through die-cutting. In the cardboard box production process, after the corrugated cardboard is formed, it enters the die-cutting stage. At this time, according to the design requirements, the mold is used to complete the punching, crease pressing, and cutting processes on the cardboard in one go. However, in some special cases, it is also necessary to punch holes a second time on the finished cardboard box during the processing.

[0004] Currently, punching holes on the outside of formed cartons mainly relies on manual operation or fixed mechanisms. Manual punching depends on the operator's experience and is prone to hole misalignment and inconsistent height due to positioning errors. It is also inefficient and difficult to scale up. While fixed mechanisms can process in batches, their mechanical structure is usually preset with fixed dimensions and positions, which cannot flexibly adapt to the personalized needs of cartons of different sizes. Adjusting the hole position or height requires frequent mold replacement or equipment readjustment, which is costly and time-consuming. Therefore, it is difficult to achieve precise and dynamic adjustment, which can easily lead to hole misalignment and limit its application in diverse scenarios.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an adjustable height cardboard box punching device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] An adjustable height cardboard box punching device includes a base; a first adjustment mechanism located at the top of the base for adjusting the vertical height of the cardboard box; a support frame located on the outer side of the first adjustment mechanism and cooperating with the base; a second adjustment mechanism symmetrically located on both sides of the support frame; a punching mechanism located on one side of the second adjustment mechanism and cooperating with the support frame; a control panel located at the bottom of one side of the support frame; a worktable located at the top of the first adjustment mechanism; the top of the worktable having anti-slip texture to prevent the cardboard box from sliding during punching; a baffle cooperating with the first adjustment mechanism located on one side of the worktable; and symmetrical square grooves on both sides of the support frame cooperating with the punching mechanism for horizontal movement of the punching mechanism along the square grooves.

[0009] Furthermore, to prevent the carton from sliding during the punching process, the anti-slip texture consists of a strip structure made up of several S-shaped protrusions connected end to end, and the strip structure is evenly distributed on the top surface of the workbench.

[0010] Furthermore, in order to adjust the height of the carton in the vertical direction, the first adjustment mechanism includes a fixed frame set at the top of the base, with a first slide rail at the middle of the top of the fixed frame; a first motor is set on one side of the fixed frame, and a first lead screw cooperating with the fixed frame is set on one side of the first motor, with a sliding seat cooperating with the first slide rail on the outer side of the first lead screw; a second slide rail is set on one side of the sliding seat; a plurality of limiting rods are evenly arranged at the top of the fixed frame, with a lifting plate inserted through the top of the plurality of limiting rods, and a limiting block cooperating with the second slide rail is set at the bottom of the lifting plate; the second slide rail forms an inclined angle with the horizontal plane, and the plane containing the line connecting the grooves on both sides of the second slide rail is perpendicular to the plane containing the line connecting the grooves on both sides of the first slide rail.

[0011] Furthermore, in order to adjust the horizontal position of the drilling mechanism, the second adjustment mechanism includes a fixed plate symmetrically arranged on one side of the support frame; a second motor is provided on one side of the fixed plate, and a second lead screw that cooperates with the fixed plate is provided on one side of the second motor; a limit groove is provided on one side of the support frame; a sliding block that cooperates with the limit groove is provided on the outer side of the second lead screw, and a support plate that cooperates with the drilling mechanism is provided at the bottom end of the sliding block; the limit groove is concave in shape, and the support plate is L-shaped.

[0012] Furthermore, in order to perform punching operations on the carton, the punching mechanism includes an electric push rod mounted on the top of the support plate, and one end of the output shaft of the electric push rod is equipped with a punching tool that mates with a square slot.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. With the combined action of the first adjustment mechanism, the second adjustment mechanism, and the punching mechanism, this utility model can adjust the punching position and the height of the carton, improving the flexibility and efficiency of production. By accurately adapting to the personalized needs of different carton specifications, it eliminates the need for repeated manual positioning or frequent replacement of fixed molds. This reduces errors and time costs caused by manual intervention and avoids resource waste caused by the limitations of preset molds. The dynamic adjustment capability ensures that the hole position and the carton height strictly match the design standards, reducing production costs and material waste, and meeting the applicability and economy of the overall optimized packaging solution.

[0015] 2. This utility model significantly improves the convenience and efficiency of operation by minimizing the vertical height of the first adjustment mechanism when adjusting the height of the carton. The lower vertical structure design reduces the overall space occupied by the equipment, allowing operators to more easily access the carton placement area and quickly complete the replacement action without frequently bending over or lifting the carton, reducing physical exertion and the risk of operational errors. At the same time, it can shorten the carton positioning path, ensuring accurate matching between the punching position and the carton height, and avoiding hole offset or carton tilting caused by excessive lifting and lowering. In addition, the low-profile design also facilitates quick switching between different batches and sizes of cartons, reducing downtime for debugging and improving the flexibility of the production line, especially suitable for customized production needs of multiple varieties and small batches.

With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, an adjustable height cardboard box punching device is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the configuration method according to an embodiment of this utility model includes a base 1; a first adjustment mechanism 2, disposed at the top of the base 1, for adjusting the vertical height of the carton; a support frame 3, disposed on the outer side of the first adjustment mechanism 2 and cooperating with the base 1; a second adjustment mechanism 4, symmetrically disposed on both sides of the support frame 3; a punching mechanism 5, disposed on one side of the second adjustment mechanism 4 and cooperating with the support frame 3; a control panel 6, disposed at the bottom of one side of the support frame 3; a workbench is disposed at the top of the first adjustment mechanism 2; the top of the workbench is provided with anti-slip texture 7 to prevent the carton from sliding during punching; a baffle 8 cooperating with the first adjustment mechanism 2 is disposed on one side of the workbench; square grooves 9 are symmetrically opened on both sides of the support frame 3 to cooperate with the punching mechanism 5, for the punching mechanism 5 to move horizontally along the square grooves 9.

[0026] By utilizing the aforementioned technical solution, this utility model, through the coordinated action of the first adjusting mechanism 2, the second adjusting mechanism 4, and the punching mechanism 5, can adjust the punching position and the height of the carton, improving production flexibility and efficiency. By precisely adapting to the personalized needs of different carton specifications, it eliminates the need for repeated manual positioning or frequent changes to fixed molds. This reduces errors and time costs caused by manual intervention and avoids resource waste due to limitations of pre-set molds. The dynamic adjustment capability ensures that the hole position and carton height strictly match the design standards, reducing production costs and material waste, thus meeting the applicability and economy of the overall optimized packaging solution. Furthermore, by minimizing the impact on the height of the carton during height adjustment... The lower vertical height of the first adjustment mechanism 2 significantly improves the convenience and efficiency of operation. The lower vertical structure design reduces the overall space occupied by the equipment, allowing operators to more easily access the carton placement area and quickly complete the replacement without frequently bending over or lifting the carton, reducing physical exertion and the risk of operational errors. At the same time, it can shorten the carton positioning path, ensuring a precise match between the punching position and the carton height, and avoiding hole offset or carton tilting caused by excessive lifting and lowering. In addition, the low-profile design also facilitates quick switching between different batches and sizes of cartons, reducing downtime for debugging and improving the flexibility of the production line, especially suitable for customized production needs of multiple varieties and small batches.

[0027] In one embodiment, the anti-slip texture 7 is composed of a strip structure consisting of several S-shaped protrusions connected end to end, and the strip structure is evenly distributed on the top surface of the workbench; thereby preventing the carton from sliding during the punching process.

[0028] In one embodiment, the first adjusting mechanism 2 includes a fixed frame 201 disposed at the top of the base 1, a first slide rail 202 disposed at the middle position of the top of the fixed frame 201; a first motor 203 disposed on one side of the fixed frame 201, a first lead screw 204 cooperating with the fixed frame 201 disposed on one side of the first motor 203, a sliding seat 205 cooperating with the first slide rail 202 disposed on the outer side of the first lead screw 204; and a second slide rail 206 disposed on one side of the sliding seat 205. The top of the frame 201 is evenly provided with several limiting rods 207, and a lifting plate 208 is inserted through the top of the limiting rods 207. The lifting plate 208 can slide along the limiting rods 207. The bottom of the lifting plate 208 is provided with a limiting block 209 that cooperates with the second slide rail 206. The second slide rail 206 forms an inclined angle with the horizontal plane, and the plane where the line connecting the grooves on both sides of the second slide rail 206 is located is perpendicular to the plane where the line connecting the grooves on both sides of the first slide rail 202 is located. Thus, the height of the carton in the vertical direction can be adjusted.

[0029] The working principle of the first regulating mechanism 2 is as follows:

[0030] The first motor 203 in the first adjustment mechanism 2 is controlled and started via the control panel 6. Under the rotation of the output shaft of the first motor 203, the first lead screw 204 is driven to rotate. Under the rotation of the first lead screw 204, the sliding seat 205 is driven to move horizontally along the first slide rail 202. Based on the fact that the second slide rail 206 forms an inclined angle with the horizontal plane, and the plane where the line connecting the grooves on both sides of the second slide rail 206 is perpendicular to the plane where the line connecting the grooves on both sides of the first slide rail 202 is perpendicular to each other, the movement of the first slide rail 202 drives the second slide rail 206 to move horizontally. Under the action of the second slide rail 206 and the limiting block 209, the limiting block 209 moves inclined relative to the second slide rail 206, so that the limiting block 209 moves vertically relative to the base 1. Under the vertical movement of the limiting block 209, the lifting plate 208 moves vertically along the limiting rod 207, thereby adjusting the height of the carton placed on the workbench.

[0031] In one embodiment, the second adjustment mechanism 4 includes a fixed plate 401 symmetrically arranged on one side of the support frame 3; a second motor 402 is provided on one side of the fixed plate 401, and a second lead screw 403 cooperating with the fixed plate 401 is provided on one side of the second motor 402; a limiting groove 404 is formed on one side of the support frame 3; a sliding block 405 cooperating with the limiting groove 404 is provided on the outer side of the second lead screw 403, and a support plate 406 cooperating with the drilling mechanism 5 is provided at the bottom end of the sliding block 405; the limiting groove 404 is concave in shape, and the support plate 406 is L-shaped; thereby, the horizontal position of the drilling mechanism 5 can be adjusted.

[0032] The working principle of the second regulating mechanism 4 is as follows:

[0033] The second motor 402 in the second adjustment mechanism 4 is controlled and started through the control panel 6. Under the rotation of the output shaft of the second motor 402, the second lead screw 403 is driven to rotate. Under the rotation of the second lead screw 403, the sliding block 405 is driven to move horizontally along the limiting groove 404. Under the movement of the sliding block 405, the support plate 406 is driven to move horizontally. Under the movement of the support plate 406, the punching mechanism 5 is driven to move horizontally along the square groove 9.

[0034] Furthermore, in order to perform punching operations on the carton, the punching mechanism 5 includes an electric push rod 501 set at the top of the support plate 406, and a punching tool 502 that cooperates with the square groove 9 is provided at one end of the output shaft of the electric push rod 501.

[0035] It should be explained that the punching tool 502 is a hollow cylindrical punching tool, usually made of high-speed steel or cemented carbide steel. Its tube wall end is designed with a sharp annular cutting edge, which is designed with a single or double sharp cutting edge to penetrate the side wall of the carton to form a regular round hole. After being energized by the electric push rod 501, the punching tool 502 is driven to squeeze in the horizontal direction, and the cutting edge is used to perform shearing punching on the carton to realize the punching operation of the formed carton.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In practical applications, the formed carton is first placed centered on the workbench, with one side of the carton in contact with the baffle 8. The anti-slip texture 7 ensures the formed carton will not slide on the workbench. Then, according to the punching requirements and process, the first motor 203 in the first adjustment mechanism 2 is controlled and started via the control panel 6. The rotation of the output shaft of the first motor 203 drives the lifting plate 208 to move vertically along the limit rod 207, thus adjusting the height of the carton placed on the workbench. After adjustment, the second motor 402 in the second adjustment mechanism 4 is controlled and started via the control panel 6. The rotation of the output shaft of the second motor 402 drives the punching mechanism 5 to move horizontally along the square groove 9, aligning the punching cutter 502 in the punching mechanism 5 with the desired punching position. Then, the electric push rod 501 is controlled and started via the control panel 6. Under the extension of the output shaft of the electric push rod 501, the punching cutter 502 punches the formed carton.

[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, the combined action of the first adjusting mechanism 2, the second adjusting mechanism 4, and the punching mechanism 5 enables the adjustment of the punching position and the height of the carton, improving production flexibility and efficiency. By precisely adapting to the personalized needs of different carton specifications, it eliminates the need for repeated manual positioning or frequent changes of fixed molds, reducing errors and time costs caused by manual intervention and avoiding resource waste due to limitations of pre-set molds. The dynamic adjustment capability ensures that the hole position and carton height strictly match the design standards, reducing production costs and material waste, and meeting the applicability and economy of the overall optimized packaging solution. Furthermore, by adjusting the height of the carton... At the same time, by minimizing the vertical height of the first adjustment mechanism 2, the ease and efficiency of operation are significantly improved. The lower vertical structure design reduces the overall space occupied by the equipment, allowing operators to more easily access the carton placement area and quickly complete the replacement without frequently bending over or lifting the carton, reducing physical exertion and the risk of operational errors. At the same time, it can shorten the carton positioning path, ensuring accurate matching between the punching position and the carton height, and avoiding hole offset or carton tilting caused by excessive lifting and lowering. In addition, the low-profile design also facilitates quick switching between different batches and sizes of cartons, reducing downtime for debugging and improving the flexibility of the production line, especially suitable for customized production needs of multiple varieties and small batches.
